About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100S
The AirTAC SAIJ100X170-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the travel. With a nominal 170 mm stroke and a 100 mm adjustment range, it provides a usable travel window of 70 to 170 mm. This bore delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa. It includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and a magnet for position sensing.
The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning, meaning it decelerates travel but does not lock or hold the load without live air. For secure load-holding without pneumatic pressure, consider the related SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100S Is Used
Variable End-Stop Tuning
Dial in the exact 70 to 170 mm travel distance during machine commissioning without physically swapping out the entire ISO 15552 profile cylinder.
Product Size Changeover
Quickly adapt automated lines to different package dimensions by adjusting the rear stopper screw to meet new physical stroke requirements on the fly.
Machining Position Setup
Establish precise retraction limits for clamping or pressing operations, using the rear stop to set the exact end position independent of the air cushion.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100S the Right Cylinder?
Choose this 100 mm bore when your application requires 3927 N of push force at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The 100 mm adjustment code on this 170 mm stroke creates a wide 70-170 mm adjustable window, ideal for machines processing varying product sizes without swapping the cylinder or adding external stops. If you need less force, a 50 mm bore offers 982 N at 0.5 MPa.
This adjustable-stroke variant is preferred over a fixed SAI cylinder when you need variable end-stops during product changeovers. It features PT tapered port threads and a G1/2 air supply connection. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 170 mm, external guiding is recommended to manage side loads on the 25 mm rod.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100S FAQ
This 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel from the 170 mm nominal stroke down to as little as 70 mm, creating a 70-170 mm usable window without changing the cylinder itself.
